I used a lot of products for this project, so including all related products in this review. Recommendation: 1) When mounting grab bars, it's always easier if you can find the stud to attach to. In this vertical install, I decided to use a stud and Wing-Its anchors; partially because I wasn't sure I could hit both, and didn't want to put two fasteners vertically (on either the right or left only), but that would also position the bar in the shower a little too far in (towards the shower control). 2) The WingIts requires a 3/4" hole through the mounting material. For tile, this can be especially challenging. I used the SHDIATOOL diamond 3/4" bit, with the DRILLAX adapter to get through the tile, and then used the 3/4" BOSCH bit to finish through the dry wall. Also used the BOSCH bits for the other small hole. Having the right tool for the job is the difference between project completion, and a messy, disaster.

I cut holes for studs in some granite slabs being attached to the front of my house to mount lights and an address to. It’s a bit of a hassle removing and plunging out the cores after each hole cut but I tried using a couple other methods which resulted in destroying the slabs. For my application, these were exactly what I needed. I ended up reaming out the wax material as it seemed to make the bit clog up more and make it difficult to get the cores out. I was able to use water instead for my project. ## Features - 1pc 1-3/8 inch vacuum brazed diamond drill core bits for porcelain ceramic tile - Diameter 1-3/8 inch(35mm); Connection: 5/8-11 arbor; Diamond height 15MM,Total height: 75MM - Machine: Angle GrinderοΌ› Remark: Max working depth: 50mm - Dry/wet drilling for porcelain tile marble stone masonry brick normal stone - High quality Diamond Grain provide fast and smooth drilling ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072148BTN | | Best Sellers Rank | #12,068 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #5 in Core Drill Bits | | Brand | SHDIATOOL | | Brand Name | SHDIATOOL | | Color | Black | | Compatible Material | Ceramic, Marble, Porcelain, Stone | | Customer Reviews | 4.6 out of 5 stars 1,796 Reviews | | Item Dimensions L x W | 2.95"L x 1.38"W | | Item Thickness | 15 Millimeters | | Manufacturer | SHANGHAI DIATOOL CO., LTD. | | Material | Artificial diamond and Steel body | | Material Type | Artificial diamond and Steel body | | Model | A854751535 | | Part Number | A854751535 | | Product Dimensions | 2.95"L x 1.38"W | | Style | Compact | | Style Name | Compact | | UPC | 718760505542 | | Unit Count | 1 Count | ## Product Details - **Brand:** SHDIATOOL - **Color:** Black - **Item Thickness:** 15 Millimeters - **Material:** Artificial diamond and Steel body - **Product Dimensions:** 2.95"L x 1.38"W - **Style:** Compact - **UPC:** 718760505542 ## Images ![SHDIATOOL Diamond Core Drill Bits 1-3/8 Inch (35mm) for Porcelain Ceramic Tile, Granite Countertop, Marble, Stone and Masonry Brick Vacuum Brazed Hole Saw with 5/8-11 Thread - Image 1](https://m.media-amazon.com/images/I/61fe9C3pvVL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bath tub grab bar install project *by A***8 on December 7, 2021* Summary: Adding a few grab bars to dad's shower.

I was able to use water instead for my project. ### ⭐⭐⭐⭐⭐ Excellent product! *by X***E on June 2, 2025* I have to admit that this drill bit is a life saver. Trying to install a RO for my daughter but the "no hole on granite countertop" was a barrier to me. Never thought it's possible to drill the hole by myself, as a minor mistake could be very expensive. However, after some research I realized it's very doable, with the right tool and caution. So I found this wonderful diamond drill bit at a very reasonable and affordable price. Received the product in the next day, and the drilling is just like cutting into butter. I'm not a pro and is at average handy. Just follow the 4 steps instruction: 1. Initialize the drill at 45 degree angle 2. In couple seconds, the drill bit does the job to cut into the stone. 3. Now while maintain the contact of the drill bit to the stone, slowly move the drill bit to upright position and continue the drill process 4. Continue the drilling while slowly swaying the drill in a cycle I did the dry drill, and in just 4 minutes, job was done!!! And, the drill bit still looks as new after it! I did read thru those reviews with bad luck. From my experience, I believe the following tips are critical for a happy result: 1. Do NOT push the drill too much. Let the drill bit, not your muscle, do the job to cut thru the stone. The weight of the grinder is enough to drive it thru. 2. Do it slowly and patiently. Time is your friend for a beautiful cut. Some other helpful tips: 1. Wear eye protector and hearing protector. It's loud! 2. Have a 2nd pair of hand to hold the vacuum around the hole to control the dust. Lastly, thank Amazon and "Made in China" to bring such affordable products. Otherwise, will have to spend 5X more easily to get pro... Overall, highly recommended. ## Frequently Bought Together - SHDIATOOL Diamond Core Drill Bits 1-3/8 Inch for Porcelain Ceramic Tile Marble Brick Vacuum Brazed Hole Saw 35mm - SHDIATOOL Core Drill Bit Adapter 5/8"-11 Thread Male to SDS Plus Shank --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/67498097-shdiatool-diamond-core-drill-bits-1-3-8-inch-35mm](https://www.desertcart.tn/products/67498097-shdiatool-diamond-core-drill-bits-1-3-8-inch-35mm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-11*
